THOMAS J. SHEARER'OF. INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE-HALF TOJAMES J. BEEOHLER, OF SAME PLACE.

CISTERN.

SPECIFICATION forming part of Letters Patent No. 521,869, dated June 26,1894. Application filed September I9, 1893. Serial No. 485,843. (Nomodel.)

To all whom it may concern.-

3e it known that I, THOMAS J. SHEARER, a c tizen of the United States,residing at Indianapolis, in thecounty of Marion and State of Indiana,have invented a new and useful Improvement in Oisterns, of which thefollowlng is a specification,

My invention relates to improvements in cisterns for the storage ofwater, of that class that are constructed from clay, burned, glazed orvitrified, in sections impervious to water and adapted to fitone uponanother, and

consists in the form of construction hereinafter described and pointedout in the claim. The objects of my invention are to produce a cisternlining that can be put in place without the assistance of skilledmechanics, that does away with the use of brick, stone 'or cement and ischeap and. durable, not likely to leak and that will prevent surfacewater from seeping in, thus insuring pure water. These objects areobtained by the construction illustrated in the accompanying drawings,wherein corresponding letters of'reference indicate corresponding partsin all the figures of the drawings. Figure 1, is a verticalse'ctionalview of th c stern as it appears when placed in positlon. Fig. 2, is aperspective view of the top section. Fig. 3 is a perspective viewof thecentral section and Fig. 4 isa perspective View of the bottom section. oThe top section A, is oval in .shape and is provided with the short neckb, the top of said neck having an angular lip c which provides the fiatsurface or seat at upon which a suitable cover can rest. The lip c, isintended to extend above the groundto a sufficient height to preventsurface water from leaking in around the cover. water inlet 6, which isprovided with a circular lip or raised ring f, there being a spacebetween the lip f and the edge of the inlet opening e. A water filterg,'can be placed near the'cistern and connected thereto by the inletpipe h. The lower edge j, of the top portion A, is made perfectlystraight and smooth.

The central sectionB is circular inshape and is provided with an angularlip c which is extended so as to leave a space is between In the top A,is the theinner edge ofthe lip, and the outer edge of the section A,when the top has been placed in position thereon. The sides of thecentral section B, are perpendicular, the lower edgej being perfectlystraight and smooth.

The bottom section 0 is oval in shape and is provided with theangularllip c", similar to the lip c on the central section B. Theobject of the space It between the inner edge of the lips c, c and c" isthat the joints may be thoroughly closed by filling the space withcement m asshown in Fig. 1.

It will be seen that the above described construction will form aperfectly water tight cistern, and that the sections can be placed inposition in a very short time without the aid of skilled labor. Theexpense of building will be greatly lessened and no unpleasant tasteimparted tothe water as does the coment ordinarily used in the brick andmortar cistern in common use. Another advantage is that the cistern canbe put to'immediate use without waiting for the mortar to dry, as is thecase with the common cistern.

It is obvious that the size of the cistern may be increased by placingone or more additional central sections between the top and bottomsections.

In the manufacture of the sections, the clay is burned and glazed orvitrified, which renders it perfectly water tight and very desirable forsanitary reasons.

The oval shape of the top and bottom sections', gives great strength tothe parts and lessens the liability of breakage in handling.

Having described. my invention, what I claim, and desire to secure byLetters Patent, 1s-

In a cistern the combination of the oval top Section having neck 19, theangular lip c, the water inlet e, having the raised ring f, theperpendicular central section B, having the angular lip o, the ovalbottom section 0, having the angular lip c, as shown and described.

In testimony whereof I have hereunto signed my name in the presence oftwo attesting witnesses, this 6th day of July, 1893.

- THOMAS J. SHEARER."
